Evening all, My main grow is currently suffering. LED Qube 1.4m x 1.4m Tent Logic 900 ( 3 x Logic 300 ) - All three Logics are set at 50% @ 20 inches Currently Flowering - 2 x San Bacio Gelato & 2 x L.A Gelato Flipped DWC - 14th Nov 2020. Currently on day 40 of flower. Nutes - Current Culture - Bloom A&B, CocoCal, UC Roots & Bud Booster mid - EC 0.9. Temps - 20°c lights off - 27°c lights on - RH 45 - 60% - with Dehumidifier running when RH rises. Everything has been running smoothly in my DWC setup until about a week ago. I noticed my ppm meter was set to ppm 700 instead of 500 so I've been underfeeding. I saw 2 plants developing brown spots and put it down to underfeeding and it being the start of week 5 flower - possible looking mag def due to low phosphorous. I increased the feed and bud booster to EC 1.0. EC was dropping over the next few days so everything seemed fine. PH was in check ranging from 5.5 - 6.2. Looking back now the PH was constantly dropping due to the low feed and since increasing the EC PH has stabilised. Noticed the leaves curling inwards and thought the fresh res change would resolve it or maybe I'd added too much bud booster. Done a fresh res change last night with a lower EC 0.9 with less bud booster. Checked again tonight and all leaves seem to be curling inwards. I can't see any pests and have sticky traps up that are fairly clean. I've got 4 weeks remaining and was wondering if there's anything i can do to fix this? Any help appreciated. Pics to follow shortly!
